The Hello singer was widely reported to be the favorite to headline the half-time show at the February 2017 event in Houston.
The multiple Grammy Award-winning singer told fans during a concert in Los Angeles that she was asked by the NFL to perform at the event in Houston, Texas, in February.
“First of all, I’m not doing the Super Bowl,” Adele said from the stage in a video posted on Twitter.
“I mean, come on, that show is not about music. And I don’t really – I can’t dance or anything like that. They were very kind, they did ask me, but I did say no.
“I’m sorry. Maybe next time, for my next album, because I’m going to do a dance album next time. So maybe I’ll do it then.”
The UK superstar was widely reported to be the favorite to play the half-time show.
In August, an NFL source was reported in The Sun as saying: “There is nobody bigger in the world than Adele right now and organizers are doing absolutely everything they can to try to persuade her to sign up.
“She’s sold out every date on her tour, everyone wants a piece of her and they know they can bank on her bringing in the viewers.”
Previous half-time shows have included a long list of famous names such as Beyonce, Madonna, Prince, Bruce Springsteen and the Rolling Stones.
